@vitor_a Pelo jeito isso é algum bug com essa versão do controller porque aqui acontece a mesma coisa. Engraçado que por 1 tempo os AP's reportam sem problema algum ai do nada começa a reportar Heartbeat Missed. Eu achei que pudesse ser algo da vlan ou firewall por serem de redes diferentes mas não me parece ser.

en-us: It looks like a bug in the Controller Version:4.1.5 because all the AP's reports as CONNECTED but from nowhere it shows as HEARTBEAT MISSED and then come back as CONNECTED without me moving a finger. At first I thought it was a VLAN/Firewall problem but I couldn't find any problems. Even if it doesn't interfere in the AP delivering connection I hope this is a controller thing that with a update could be fixed because everytime I need to access the controller I have a little scare seeing the HEARTBEAT MISSED.
